[0020] The concept, specific structure and generated technical effects of the utility model will be clearly and completely described in combination with the embodiments and drawings, so that the purpose, scheme and effect of the utility model can be fully understood. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other without conflict. The same reference signs in the drawings indicate the same or similar parts.

[0021] It should be noted that, without special instructions, when a certain feature is referred to as "fixed" or "connected" to another feature, it can be directly fixed or connected to another feature, or indirectly fixed or connected to another feature. In addition, the up, down, left, right and other descriptions used in the utility model are only relative to the mutual position relationship of the components of the utility model in the drawings.

[0022] Reference Figure 1The utility model provides a kind of tool for motor train set toilet sewage tank float ball dismounting, including hollowly arranged sleeve 1 and sleeve 2, the sleeve 2 is fixed in one end of the sleeve 1, the inner wall 22 of the sleeve 2 away from the end of the sleeve 1 section matches with sewage tank float ball mounting seat, so that float ball mounting seat can be embedded in the sleeve 2, and during the rotation of sleeve 2, it will not be relatively moved or slip with sleeve 2.The sleeve 2 is also provided with groove 21 in this end, the notch of the groove 21 is communicated with the opening of the sleeve 2 this end, the setting of groove 21 can pass through groove 21 or extend outside sewage tank after passing through groove 21 when using, can guarantee that damage is not caused to connecting line during dismounting, and the loss caused during dismounting can be reduced.

[0023] Sleeve 1 can extend the length of sleeve 2, so that the overall length meets the dismounting operation of float ball from sewage tank access hole, sleeve 1 adopts the design of long straight pipe, simple structure, easy to manufacture, can also avoid the mistake of bumping and damaging other equipment in sewage tank access hole during operation in narrow space.The sleeve 2 is matched with the float ball installed on sewage tank, to ensure the stability during dismounting operation, avoid the risk of damage to the internal chip of float ball caused by uneven force during dismounting, reduce material loss and improve dismounting efficiency.

[0024] When dismounting motor train set sewage tank float ball, float ball mounting seat is usually hexagonal bolt structure, the sleeve 2 of the present application is connected with the sewage tank float ball mounting seat to be dismounted, the connecting line of sewage tank float ball is passed through or extended, and then tool is inserted into the through hole 11 of sleeve 1 to rotate, so that sewage tank float ball can be easily dismounted.

[0025] Specifically, the length of the groove 21 is 13mm-18mm, and the width is 6mm-10mm, when the sleeve 2 is connected with the float ball seat, the connecting line on the float ball seat can be aligned with the groove 21 and embedded in the groove 21, or the relevant connecting line on the sewage tank can be passed through the groove 21 and placed outside the sewage tank, so that the connecting line can be taken out through the groove 21 during use, which can ensure that the connecting line is not damaged during dismounting, and the loss caused during dismounting can be reduced.The length of the groove 21 can be preferably 15mm, and the width can be preferably 8mm.

[0026] Specifically, the end of the sleeve 1 away from the sleeve 2 is provided with four through holes 11, and the four through holes 11 are distributed in the circumferential direction of the sleeve 2, and the four through holes 11 are uniformly distributed around the axis of the sleeve 1, so that the tool can be inserted into the through hole 11 to assist the rotation of the sleeve 1 during the rotation of the sleeve 1.

[0027] Specifically, the fixture for disassembling the float ball of the waste tank in the high-speed train's toilet also includes a handle. One end of the handle can be inserted into a through hole 11. The handle can be a straight rod structure, which is simple and easy to manufacture. The handle makes rotational disassembly and assembly easier, improving work efficiency and saving maintenance and labor costs. Using the handle to assist in rotating the sleeve 2 prevents the sleeve 2 and other tools from falling off when rotated by hand, ensuring the safety of the operators. When disassembling the float ball of the waste tank, the operator uses the sleeve 2 to match the float mounting seat and rotates the sleeve 1 using the handle and other operating tools to achieve rapid rotational disassembly. This reduces wear and tear on precision components caused by human error during disassembly, reduces parts consumption, improves disassembly efficiency, and saves maintenance and labor costs.

[0028] Specifically, the diameter of the through hole 11 is not less than 10mm, so that one end of the handle can be smoothly inserted into the through hole 11. If the diameter of the through hole 11 is too small, it will be inconvenient for the handle to be connected with the through hole 11.

[0029] Specifically, one end of the sleeve 2 is fitted onto the outside of the sleeve 1 and welded to the sleeve 1. During the rotation of the sleeve 1, the sleeve 2 will not slip or move relative to the sleeve 1.

[0030] Specifically, the length of the sleeve 1 is not less than 380mm, and the length of the sleeve 1 is preferably 400mm. When the sleeve 2 is connected to the float seat, the end of the sleeve 1 away from the sleeve 2 can protrude outside the waste tank, and each through hole 11 can be placed outside the waste tank so that the handle can be inserted into the through hole 11. By rotating the sleeve 2 with the handle, the float of the waste tank can be easily installed and removed.

[0031] Other aspects of the tooling for disassembling the float ball of the waste tank in the toilet of a high-speed train, as described in this utility model, are found in the prior art and will not be repeated here.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
